The raw_events endpoint is provided as-is.
For past events we recommend consuming transport_events.
Get a list of past and future (estimated) milestones for a container as reported by the carrier. Some of the data is normalized even though the API is called raw_events.
Normalized attributes: event and timestamp timestamp. Not all of the event values have been normalized. You can expect the the events related to container movements to be normalized but there are cases where events are not normalized.
For past historical events we recommend consuming transport_events. Although there are fewer events here those events go through additional vetting and normalization to avoid false positives and get you correct data.
